I tried the new "hide restricted" MyList feature and I noticed that some hentai stuff isn't getting hidden. Is that a bug in the feature or does something need to be set in the individual anime?

For example, on my MyList "Accelerando: Datenshi-tachi no Sasayaki" and "Ai Doll" are both visible when they shouldn't be, however "2x1" and "Ai Shimai Tsubomi... Kegashite Kudasai" are both hidden correctly. Also, the first two anime are not shown if you use "hide unrestricted", so it's as though they're unrestricted. I checked, and they both now have "Audience::18 Restricted" set in their categories (though I had to add that for "Ai Doll", which only had "Genre::Hentai" set.)
